Michael Douglas and Catherine Zeta-Jones back together

Catherine Zeta-Jones and Michael Douglas are back together according to the 69-year-old’s mother, Diana Dill.

Six months after announcing that they were taking a temporary break in August 2013, 91-year-old Diana told The Sun that there was “too much affection” between Michael and Catherine that meant they couldn’t go their separate ways.

“They are together. I knew they would work it out,” said Diana. “They’re both gentle people, not hysterical. They’re always very affectionate and easy with each other. I figured the more everybody stayed out of it, the better.”

“They spent three long vacations together. Something’s working,” she added. “They went to Canada, they have a place in Quebec, they went to Bermuda and they went to the Caribbean with the kids on vacation. They’ve had a lot of time in the last two months.”

Catherine and Michael, who have two children Dylan, 13, and ten-year-old Carys, are also living together as a family again.

Diana cites part of the reason Michael and Catherine have decided to give their marriage another go is that the One Flew Over The Cuckoo’s Nest star has been beginning to understand his wife’s battle with bipolar disorder.

“It’s probably not an easy thing to understand if you don’t have it yourself,” said Diana, who described her Welsh daughter-in-law as “open and funny”. “But he’s an understanding person.”

While the couple didn’t officially confirm that their 13-year marriage was getting back on track, they hinted that things were going well.

When Michael won a Golden Globe for Best Actor for his role in Behind the Candelabra, the 69-year-old took the opportunity to thank Catherine and their three children.

“To Catherine, Carys, Cameron and Dylan – all my love,” said tuxedo-clad Michael as he accepted the gong, also mentioning his son Cameron from his previous marriage.

He also commented that things were on the “up and up” during an interview with chat show host Jay Leno.
